Hi,
I am updating our system from Kernel 4.6 to 4.9 (and Debian). After some issues the system runs very well. The only problem is, after logging in an press tab I got a message.
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

I see this message only after the first time I press tab and only when I am connected via a serial connector. After I got the message I can find this entry in dmesg
dmesg | grep -i 'taint'
[ 97.586696] CPU: 1 PID: 1406 Comm: bash Not tainted 4.9.0-xilinx #5
If I change the shell to sh the problem dissapears. But I have to use the bash shell.
Does anybody have an idea to fix this problem?
Thanks
Ryzen
